Objective To investigate the correlated clinical factors of upper gastrointestinal hemorrhage induced by acute organophosphorus pesticide poisoning(AOPP) and look for effective method for the prevention and treatment of upper gastrointestinal tract bleeding(UGTB).Methods 49 patients with severe AOPP were divided into UGTB group(group A,26 cases)and non-UGTB group(group B,23 cases).The time,frequency and causes of UGTB were observed.We also observed the differences in acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ),blood glucose and cholinesterase in serum.Results The causes of UGTB induced by AOPP were poison damage of stomach mucous membrane,gastric lavage damage and irritability ulcer;APACHE Ⅱ scores of group A were more than those of group B obviously;the level of cholinesterase was lower in group A.Correlation analysis showed that the APACHE Ⅱ scores had positive correlation and the level of cholinesterase had negative correlation with UGTB induced by AOPP.Conclusion Both the APACHE Ⅱ scores and level of cholinesterase can reflect the UGTB induced by AOPP.Active treatment of the primary disease and stress status and often the operation of gastric lavage are important ways to prevent and treat UGTB induced by AOPP.

Objective To investigate the incidence of systemic inflammatory response syndrome(SIRS)after cardiopulmonary resuscitation(CPR)and to observe the effect of ulinastain in inhibition of inflammatory mediator.Methods Thirty-two patients surviving more than 72 hours after CPR were divided into ulinastain group and control group randomly.Activity of TNF-? and IL-6 of these patients was detected.In the meantime,all patients were evaluated by SIRS diagnosis and all data were compared between two groups.Results Activities of TNF-? and IL-6 in patients after CPR were significantly higher than that of normal people(P

Objective To observe the effect of valsartan on brian ultrastructure, Klotho gene and micro-inflammatory factor [intercellular adhesion molecule-1(ICAM-1) and vascular cell adhesion molecule-l(VCAM-1)] expression in spontaneously hypertensive rat models. Methods Ten male spontaneously hypertensive rats of 22 weeks age were selected and randomly divided into a hypertension group and a valsartan intervention group, while another 5 Wistar-kyoto rats were set as a normal contrast group. The brain ultrastructure of the 2 groups was observed by electron microscope. The expression of micro-inflammatory factor (ICAM-1 and VCAM-1)and Klotho gene was detected with RT-PCR, immunohistochemistry, and Western blot, respectively. Results The cerebral neuron damage of spontaneously hypertensive rats whose ultrastructure showed cell-pyknosis, chromatin margination and typical apoptotic body formation were alleviated after the intervention of valsartan. RT-PCR showed that the gene expression of Klotho increased while ICAM-1 and VCAM-1 decreased after valsartan intervention. Immunohistochemistry and Western blot also showed that the protein expression of Klotho increased, while ICAM-1 and VCAM-1 decreased after valsartan intervention. ConclusionValsartan can improve the brain ultrastructure of spontaneously hypertensive rats by increasing the expression of Klotho.

Objective To explore the changes of the Klotho protein expression in blood serum of hypertensive patients with brain harm,so as to investigate the incidence mechanism of brain harm caused by hypertension and the associated risk factors.Methods The research objects were recruited from the hypertensive in-patients and healthy individuals from health examination during September 2007 to March 2008 in our hospital.There were 56 hypertensive patients without syndrome,104 hypertensive patients with brain harm,and 30 normal control individuals,They all were marched in sex and age.Klotho protein concentration of blood serum,cholesterin,creatinine,blood glucose and blood pressure of these 3 groups were tested.And correlation analysis of the above factors and the patients' ages and hypertension medical records was performed.Results The Klotho protein concentration of blood serum in the normal control group was obviously higher than that of the hypertensive patients without syndrome and those with brain harm(P

Objective To evaluate the CT findings of the parotid basal cell adenoma and it's diagnostic value.Methods The CT appearances of 10 patients with parotid basal cell adenoma confirmed by histopathology were reviewed retrospectively.The plain and the contrast-enhanced CT scan were performed in all cases.Results The well-defined mass in varied size with marked enhancement in contrast-enhanced CT imagines,in which the CT value increased to 200Hu maximally(average,84Hu),were the pathognomonic CT characteristics of the parotid basal cell adenoma.Conclusion The qualitative diagnosis of the parotid basal cell adenoma could be made based on the CT findings combined with some valuable clinical information before operation.

Objective To investigate the possible mechanisms of teratogenesis caused by passive smoking, temporospatial changes in surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it were explored. Methods The pregnant golden hamsters were randomly divided into the treated group and the control groups. In the chamber made by ourself for passive smoking experiment, the animals of the treated group were exposed to smoke from embryonic day 4 to 7, 3 times per day for 4 consecutive days. At twelve o'clock and eighteen o'clock of embryonic day 8, eight o'clock of embryonic day 9 and eight o'clock of embryonic day 10 respectively, the pregnant golden hamsters of both treated group and control group were sacrificed, the uteri were removed and embedded routinely with paraffin, sectioned transversely in series. The sections of each group were stained with immunohistochemical ABC method and concannavalin agglutinin (ConA) and ulex europaeus agglutinin (UEA) were used as molecule probes to conduct the qualitative and quantitative analysis of the fibronectin and the related surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it. Results During embryonic day 8 to10 of golden hamsters fibronectin reduced(F=30.168,P

Objective To investigate the apoptosis in neural epithelium induced by passive smoking. Methods By using the nuclear fast red-crystal violet staining method and situ TUNEL technology, the quantitative changes of apoptosis in neural epithelium in gold hamster were analyzed. Results Excessive apoptosis and less cell division were observed in neural epithelium compared with the control group. On 9th days of pregnancy, there were most apoptosis cells, the apoptosis index was 9.82 ?3.35 which is statically significant compared with control group (P

Objective To explore the expression of Bcl-2 and Bax in embryonic neuroepithelial cells in Golden hamster exposured to the teratogenic dose of alcohol. Methods The experimental pregnant golden hamsters were given ethanol through intraperitoneally injected, 5.8 g/kg body weight. The Bcl-2 and Bax expressions in neuroepithelial cells of experimental and control animals were detected with immunohistochemical and image analysis at 4,8,16,24,48 and 72 h time points after treatment. Results Bcl-2 and Bax proteins distributed in nuclear membranes and cytoplasm of the neuroepithelial cells as well as mesenchymal cells. In control groups, the expressions of these two kind proteins increased as the time passed at beginning, 16 hours after, came to the summit and then descended gradually. Compared with the control, the expressions of Bcl-2 in experimental groups were down-regulated, expressions of Bax were up-regulated except at 8 h time point. Conclusion Alcohol can induce down-regulation of the expression of Bcl-2 protein and up-regulation of the expression of bax protein, which may play a an important role in regulation of apoptosis in alcohol-induced neural tube malformation.

Objective To observe the analgesic effects of patient-controlled intravenous analgesia (PCIA) and continuous infusion of morphine into epidural space(CIEA) after suprapubic transvesical prostatectomy. Methods Seventy-five patients undergoing suprapubic transvesical prostatectomy were randomly assigned to PCIA group,CIEA group and control group. In PCIA group, 2 0mg/h morphine as a recommended dose would be injected intravenously by the patient through a self-controlled analgesic delivery system in which another 1 mg morphine could be injected whenever patient felt pain until the pain relieved. The lockout time was 20 minutes. In CIEA group, 0 08 mg/h morphine was injected into epidural space. 50～75mg of pethidine was injected whenever the control group patients felt pain. VAS(vision simulate score), frequency and duration of bladder spasm, discontinuance time of bladder irrigation and BP were observed. Results The CIEA and PCIA group were superior to the control group with characteristics of stable analgesic effect, shorter duration and lower frequency of bladder spasm and shorter time of bladder irrigation(P0 05); but the PCIA group had longer gastrointestinal function recovery time(P
